1.4 Actual performance data
Use OUTDOOR UNIT CAPACITY TABLES.
Determine correct table according to the outdoor unit model and combination ratio.
Enter the table at given indoor and outdoor temperature and find the outdoor unit capacity and power input.
The individual indoor unit capacity (power input) can by calculated as follows.
IUC=OUC × INX/TNX
Notes:
IUC: Each indoor unit capacity
OUC: Outdoors unit capacity
INX: Each indoor unit capacity index
TNX: Total capacity index
Then, correct the indoor unit capacity according to the piping length.
If the corrected capacity is smaller than the load, the size of indoor unit has to be increased and repeat the
same selection procedure.
1.5 Cooling capacity modification in accordance with the length of refrigerant pipe
Modification coefficient of the length and height difference of refrigerant pipe:
1.5.1 Cooling capacity modification
L: Refrigerant pipe equivalent length
H: Height difference between outdoor and indoor unit. Positive data means outdoor unit is higher. Negative
